Thank you very much for the input,
@Dave !
After looking for more info in the Snow Peak Grill Burner, it seems like it would be another one-trick pony, and I already have several of those. Gonna pass on it.
After decades of backpacking and car camping, I've used a huge assortment of stoves. Most have been solo other than the Coleman white gas, and no problem with supply there; I bought out the local Kmart at a big discount when they closed, so have 8 gallons on the shelf in the garage!
My '70s era Peak One and MSR used it, too. I converted the Coleman to propane using a $12 kit, but it doesn't work great. Cheaper than buying a crap new Coleman propane, stove, though.
I've been all over on possible changes to my heat source before and since writing the above post. Actually, you can probably spin it off to an different thread to keep the Snow Peak thread cleaner. I was the one who commented on your new Kovea about looking like a cleaning nightmare. I can't find any info on cooking area on it, but it looks smallish. Too small for 4 eggs and 1/2 a pound of bacon, or several flapjacks. They make a deluxe double stove that looks interesting, but not available anywhere.
I know absolutely zero about the rattle-can shaped Butane canisters and stoves. Are they threaded, or held in place by the stove. Can a partially used canister be removed? How does the burn time compare to an equivalent isobutane canister? Can it use a propane converter like the isobutane stoves can use? I sorta like the idea of a couple Kovea Cubes that could be combined under a flat skillet. Better yet if they could be adapted to a "Y" propane hose and a 1# canister.
I've also looked again at Partner Stoves. 5 years ago, the 22" was $275, and it is double that now if you can find it. Apparently one of the partners died at the end or 2020. Looking now, there's only a couple of stoves on their website, and almost everyone online shows sold out on the 18" model, which would be closest to my Coleman. I haven't found any reviews of the Snow Peak Double Burner stove. Camp Chef seems to have garnered a mediocre quality report of late, so there's not much stuff out there to last a generation that I've found.
Tossing things around in my head, I've even considered using some 80/20 extrusion to duplicate the Snow Peak IGT style to mount on the legs of my ALMS Guide Table, allowing me to take advantage of the much more adjustability in the legs. But that still leaves be with the large bulky legs to store in the trailer. (4" X 6" X 32" folded and about 20#)
Can someone with an IGT take some measurements for me?
Frankly, with Deb tied to campgrounds with toilets, I might as well leave the Skottle, Coleman stove, JetBoil, propane, white gas, isobutane, my cast iron skillet and pot home, and just take her 40 year old electric skillet and my cheap electric tea kettle, and save a ton of space and money.
Thanks for letting me ramble...
[EDIT] I started writing this yesterday, and just got back to it this morning. So you've answered some of my butane questions already.
